CDKs / Seliciclib: Not much thought on this drug, but let me point out a neat feature of seliciclib that shows why i was skeptical of targeting CDKs: - as you note, CYCC says it hits CDK2, 7 and 9 - www.caymanchem.com/app/template/Product.vm/catalog/10009569 Cayman says it hits CDK2, 5, 7 and 1 - www.enzolifesciences.com/BML-CC205/r-roscovitine/ Enzo says it hits CDK1, 2 and 5 I guess the consensus is that it hits CDK2, with a dash of CDK1, 5, 7 and 9 :-)
